As you can see, the equation above is actually a recurrence relation, since it is an equation that, together with the initial term (i.e., f 0 = 1), recursively defines a sequence (i.e., the factorial function, f n). 10, Solved program can be found on this link http://cssimplified.com/c-programming/a-c-program-to-find-all-armstrong-numbers-in-the-range-of-0-to-999, http://cssimplified.com/c-programming/write-a-recursive-program-in-c-to-find-whether-a-given-five-digit-number-is-a-palindrome-or-not-10m-dec2005, http://cssimplified.com/c-programming/a-c-program-to-find-all-armstrong-numbers-in-the-range-of-0-to-999, draw. Whenever a function calls itself, creating a loop, then that's recursion. Depending on the implementation, what would happen the first time FACTORIAL(N) calls itself is that the memory address of the function together with n-1 would be pushed on to the stack. The following example calculates the factorial of a given number using a recursive function − Live Demo #include unsigned long long int factorial(unsigned int i) { if(i <= 1) { return 1; } return i * factorial(i - 1); } int main() { int i = 12; printf("Factorial of %d is %d\n", i, factorial(i)); return 0; } 1. We already know how to get the factorial of a number in other languages. I made mistakes during a project, which has resulted in the client denying payment to my company. But while using recursion, programmers need to be careful to define an exit condition from the function, otherwise it will go into an infinite loop.
